UNITED STATES f ieiatis ANTON YURKoViToi-i, oF PTTTsBURGH, rnNNsYLvANIA ADJUSTABLE FLUE CONNECTION v` Application iled December 29, 1931.V Serial No. 583,629.V

has been bothA complicated and unsatisfacl tory. One especially noted disadvantage was thatthe arrangement was not suchas would accommodate stove pipes of different diameters nor would yit accommodate stove pipesk entering the chimney at dilierent angles resulting from limitations'of space and size. Still other prior structures were not so disposed that they would-remain permanently in the initial position but would move or turn eventually until the connection wasloosened and hence would leak. Other disadvantages are known to those working in this art and need no further discussion here.

One of the objects of the present invention is ,the provision of an adjustable flue connection which overcomes the above noted andV enteringr from different angles from the hori-r zontal.

More specically my invention has for an object the setting of a ring shaped member in the room side of the chimney so' constructed and arranged that the member cannot move and at the same timecan receive stove pipes of different diameters entering from difl`erent directions and maintain the latter permanently-in position. 'A I Other and' furtherobjects and advantages will either be pointed out hereinafter or will be apparent to those skilled in this art.

Fig. 3 is a fragmentary portion looking made. v s Y Y Fig. t is a sectional view of the fastening meansand spacer showing the saine in position' with respect to'fra'gmentary sections of the stove pipe and ring; andv .l i

Fig. 5 is a section through a modified form of spacer. Y Referring now to the drawing in detail, represents. a fragment of the brickwork ofa chimney or the like looking 'at theroom side thereof. Embedded in this briokwork is the ring-shapedmember or annulus 11 `which is made ofV a suitable metal and which,ifv preferred, is' provided atthe front edge thereof with a relatively narrow upstandiiigiiange 12 extending at right angles. approximately to the body of the annulus. This annulus or ring-shaped member 11 may either beseamfrom the center of the :device toward the wall i thereof at the` point where the connection is less or may be made as shown from ablank which is bent around into ring shape and the edges or seam 13 welded in any desired way. This rin g-shaped member 11 isprovided'with diametrically opposite key-hole slots 14 having their enlarged; portion towardthe front i edge of the device. Y On the outsidefoffthe ring-shaped member 11 are the twofbox-likeshields 15, these shields being alsodiametrically opposite and overlying the key-hole slots 14: aforesaid. These shields 15 may be shallow box-like members Vbent up from suitable'blank's. They have side flanges 16by means of which theshieldsaresecured to the ring-shaped member l1. f-The connection may be by means of rivets` li'. orinay be byfbrazing, welding, or the like; oi-ci-n any other avail- 9 able manner. These *box-like" shields 15 not (Y only provide diametrically oppositeiprojec` tions on the outside ofthe ring-shaped mein-` ber 11 but at thesame time they'vprote'ct the key-hole slots 14 from' being clogged with mortar, chips of brickV orsthe'like thus preventing their functioning inthe'mannerto Y be, described. f

A terminal section of stove pipe-18, for ei;n i

ample7 may be l'connected to thefring-shaped member 11 so that the stove y'pipe section 1S is centrally disposed relativeto the` ringffsh aped' member 11 and so that the section'lS may be given any desired angularrposition*fromthe n horizontal, thus adapting thesame for con.-

vil

nectioii with any stove pipe regardless of the angle from the horizontal which vrit assumes due to size or space limitations in the room oi' relative to the members themselves. This stove pipe section 18 is provided at its rearward edge with the 'diametrically opposite slots 19 which are clearly shown in thY drawing. The stove pipe section may be any conventional or desired material either seamless or provided with an overlapping seam 20. 1With respect both to the stove pipe sec` tion-18 and the ring-shaped member 1l, the existence or absenceof a seam is immaterial so that either seamless tubing or blanks bent and fixed into tube shape may be utilized.

The means for maintaining the stovev pipe` section 18 in place is shown particularlyv in Fig. 4. The means comprises a bolt 21l having threads 22 throughout its length and an enlarged, slotted head 23 in the usual many ner, but the bolt 21 is square, not round, as

y made even larger.

clearly appears from Fig. 8 and as is also understandable from j Fig. 4 wherein the threads 2,2 of the bolt are also shown as being only on the corners and not on the sides of the bolt. Such a bolt may be made initially in this manner or it may be made by tiling down an ordinary round threaded bolt into square shape. Such an operation would generally remove the threads from the flattened sides of the bolt leaving the threads only on the corners. For use with this bolt is the wing nut 24 which is of course, internally threaded. yA washer or 'other similar member 25v is also utilized for the usual purposes. A spacer member 26 is also provided which in the example sliown positions lthe members as they appear in the drawing'. This spaceris, however, variable as to size, that is, a spacer is chosen of such a length asto meet certain requirements Vwhich will be now set forth. Such a modified form of spacer is shown at 27 in Fig.l 5. The spacers are preferably ot metal. v

In General it has been found that stove r o Y pipes vary from a rather small diameter to about seven inches as a maximum. I, therefore make the diameter of in rin sha )ed i member 11 more than seven inches and in general the diameter *need be only a little more and in a typical example my ringshaped member has a diameter of 'T1/ 5. This permits the ring-shaped memberv to accominodate stove pipes up to'the maximum size generally used but, ofcourse', in Special instances, where larger pipes are `to'be accommodated the ring-shaped iiieinbe'r can V`be Depending upon what size of stove pipe-Visto bei connected a spacer is chosenwhich represents the diiierence, that member 11 is embedded in the briclwork 10 Y2 j i 1,919,678

of a chimney substantially flush with the room side thereof and the flange 12 lays flat against the briclrwork .sealing the joint. Mortar may, for example, be placed under the flange, but iii any event, the ring-shaped member cannot rotate or move in the brickwork because the box-like shields 15 are firmly fixed in the mortar and bricks to prevent even the slightest movement. The heads of the bolts are passed into the enlarged foi'- ward portion of the key-hole slots and then slid toward the rear, the square slianlrs ot the bolts preventing the bolts themselves from turning in the slots after they are in the slots as is clearly indicated in Fig. 3. The spacers 26 or 27 or spacers oi proper size can then be placed on the bolts, and the proper size of spacer is selected for Jthe particular case, whereupon the stove pipe section 18 is passed into the ring-shaped member so that the shanlis of the bolts pass into the slots 19 in the rear edge of the stove pipe section 18 and the stove pipe section is pushed inwardly until the bolt shanks abut the extremities of said slots. The washer members 25 are then placed over the ends of the bolts and lthe ring nuts 24e finally put in place and tightened. It will be seen thatthe stove pipe section 18 can be pivoted about the bolts so that it can be given any necessary or desired angular position froml the horizontal thus enabling it to receive the'next section of a stove pipe from a stove in any position which said stove may take in a room. The stove pipe leading from the stove (not shown) telescopes with the forward end of the stove pipe section 18 iii the usual manner. Y

It will thus be apparent that I have provided a simple device which is inexpensive and yet which is fully adapted to effect the functions toiI which it was designed; Furthermore, the' construction is such as to connect with stove pipes at any angle from the horizontal within wide'limits and moreover stove pipes of considerably different sizes can `be accommodated'. The device can be made up as a unit shown in Fig. 1 (either wither without stove' pipe section 18)l and sold in that form at a 'very moderate price and can then be placed in the briclrworl of'a chimney without dithculty.' My invention'is pai'- ticularly adapted for use in building new houses so that the'ring-shaped member 11 can beV built directly into the briclwork oit the chimney as the latter is construct-er The above is intended tosbe illustrative only and is not to be taken in a limitative sense other than as determinable by the subjoined claims. The memhers'11 and 18 might be other than round, or either or both might be non-round, to meet special Vconditions or designs. j 7
